This report delves into the fundamental concepts of force and motion, defining force as the cause of motion, and categorizing forces into pushes and pulls, including gravity and friction. It explains how forces measured in Newtons can affect objects by changing their speed, direction, and shape. The distinction between balanced and unbalanced forces is highlighted, along with the role of friction. Additionally, the report covers Newton's three laws of motion and the difference between speed and velocity, introducing key formulas related to energy transformation.

Reporting Category 2 Force and Motion
First we need to define the word FORCE: • The cause of motion (what causes objects to move) • Two types of forces • Pushes • Pulls (Gravity, Friction)
Forces are measured in Newtons • SI unit of force • Symbol: N • Measured by using a spring scale
How Can Forces Affect Objects? • Slow them down • Speed them up • Stop them • Start them • Change their direction • Change their shape
Explain Balanced Forces • When all the forces acting on an object balance each other • Balanced forces do not cause a change in motion (no movement)
Describe Friction • Force that resists motion between two touching surfaces (sandpaper) • Acts in the opposite direction of the object’s motion • Produces heat
Sir Isaac Newton • Born Jan. 4, 1643 in England. • As a young student, Newton didn’t do well in school. • He worked hard and continued his education. • Later in life, Newton contributed ideas that became law in the worlds of science and math.
Distinguish Between Speed and Velocity • Speed describes distance and time • Velocity describes distance, time, and direction
